In terms of color that's actually really good. Not the most original thing I've ever seen, but far from the worst. Try doing some modifications to the clothes next time if you want to make a truly original sprite. I know what he normally looks like because I have worked with that sprite before-see my cosplayers. And another comment- his right arm is a little too thick and you may want to modify that hand to look like it's more on his hip. Good luck!
